- Which of these amino acids has a hydrophobic side chain?arrow_forwardThe pH at which the concentration of the zwitterionic form (dipolar form) of an amino acid is at its highest and the concentrations of the cationic and anionic forms are equal is called the ___.arrow_forwardWhich of these molecules is not a natural amino acid?arrow_forward
- What is the actual chemical component for an anthocyanin (assume a cyanidin structure), and a carotenoid (assume a lutein structure), and indicate what is the common feature of these indicators that could act as an acid or base. (While the structures are complicated molecules, compare with acetic acid, CH3COOH, a weak acid).arrow_forwardWhich amino acid is hexagonal close packed? is it glycine?arrow_forwardDraw the sequential transition of glutamic acid as it passes from its fully protonated form to its fully deprotonated form as the pH rises. If the pH of an amino acid solution is lowered by adding an acid, like , the group of glutamic acid accepts the proton, acid, to form a positive ion.arrow_forward
- 22-53 Do iron and zinc ions play role in protein structure? If so, what is the role for either or both?arrow_forwardConsider the tripeptide leucylvalyltryptophan. a. Specify its structure using three-letter symbols for the amino acids. b. How many peptide bonds are present within the peptide? c. Which of the amino acid residues has the largest R group? d. Which of the amino acid residues, if any, has a basic side chain?arrow_forwardOn complete hydrolysis, a polypeptide gives two alanine, one leucine, one methionine, one phenylalanine, and one valine residue. Partial hydrolysis gives the following fragments: Ala-Phe, Leu-Met, Val-Ala, Phe-Leu. It is known that the first amino acid in the sequence is valine and the last one is methionine. What is the complete sequence of amino acids?arrow_forward
